Feat: Add pre-commit policy conflict diagnostic (all conflicts at once, with verbatim quotes) - #809
Conversation
Document the read-only pre-commit conflict diagnostic (issue #154) across the AIAC requirement specs, ahead of code. Add a dedicated sub-PRD (policy-conflict-check.md) covering the interface, diagnostic-assembly pipeline, ConflictReport/status contract, testing tiers, and acceptance criteria; thread cross-references through the PRB sub-PRD, the AIAC Agent component PRD (endpoint, use case, file structure), and the master PRD (component summary, architectural decision, agent capability). The live /apply -> 422 contradiction path is unchanged. Assisted-By: Claude (Anthropic AI) <noreply@anthropic.com> Signed-off-by: Anatoly Koyfman <anatoly@il.ibm.com>
Extract the focal-entity resolution inlined in ServicePolicyBuilder.build() into a standalone resolve_focal_entities(service_id, service_type) -> FocalEntitySet in agent/shared/focal_entities.py, callable by both the live builder and the upcoming policy-conflict diagnostic. Pure extraction, no behavior change to the live /apply path: existing builder tests pass unchanged. The HTTPException(502) (IdP unreachable) / HTTPException(404) (unknown service) boundary moves into the resolver, where the diagnostic's pre-survey HTTP boundary needs it. builder.py keeps routing service_type through its parameter (not focus.type), preserving the live /apply contract.

Add agent/policy_rules_builder/diagnostic_models.py with the ConflictReport / Conflict / Unevaluated models, the EntityRef / FocalRef refs, and the FocalType / ConflictKind / ConflictStatus / UnevaluatedReason enums -- the stable structured shape the diagnostic engine, survey use-case, and route all serialize. Encodes the pinned focal{name,id,type} / role{name,id} / scope{name,id} / granting_quotes / prohibiting_quotes / quotes_verified contract.
Includes ConflictReport.derive_status / from_survey encoding the status precedence (conflicts_found > incomplete > no_conflict) for the survey use-case to apply. The live /apply models (Contradiction, AuditVerdict) are untouched -- no kind field added to shared models, per D11.

Add agent/policy_rules_builder/diagnostic.py: a parallel diagnostic graph (START->seed->propose->precheck->audit_diagnostic->{explain|retry|END}) that reuses the live proposer/precheck/_structured_call unchanged but seeds policy_text from input (no file read), RECORDS genuine contradictions instead of raising, marks non-converging entities unevaluated, and adds a terminal explain node. The explain node classifies kind in {direct, coarse_scope} (D11), extracts verbatim granting/prohibiting quotes validated by a whitespace-normalized substring check, and does the name->id join + run-direction tagging (D12). On quote-validation failure the conflict is kept with quotes_verified=false and the auditor description as fallback.
Adds build_explain_messages to prompts.py (append-only). Exposes run_role_diagnostic / run_scope_diagnostic per-entity entry points returning DiagnosticResult(conflicts, unevaluated) for the survey use-case to fan out over. The live graph.py is byte-for-byte unedited; the live /apply -> 422 path is untouched (D14).

Add agent/uc/policy_check/check.py::check_policy_conflicts(policy_text, service_id) -> ConflictReport: a sequential, read-only survey that runs every focal entity of the target service through the diagnostic graph to completion (the first conflict never aborts), accumulates all conflicts + unevaluated entries, and derives status via ConflictReport.from_survey with the zero-evaluated guard. service_type is derived read-only from the IdP catalog (focus.type of the service resolved by id) -- Provision is never run, so the survey never mutates IdP state. The resolver's HTTPException(502/404) pre-survey boundary is preserved on both the type lookup and resolve_focal_entities. Fan-out mirrors builder.py exactly (scope-focal over own_scopes; role-focal over flatten_role(own_role) x other_scopes for AGENT). A found conflict returns a report, never raises. Refs #158.

Thin serialization shell over check_policy_conflicts: any completed survey returns 200 with the ConflictReport JSON body (the controller's first JSON response body). Unlike the live /apply path, a found conflict is a recorded diagnosis and never 422; the resolver's pre-survey HTTPException(502/404) propagates unchanged as a bare non-2xx with no report body, and a missing policy_text is a FastAPI validation 422. The /apply routes and the PolicyContradictionError/PolicyRulesBuilderError -> 422 handlers are untouched. Refs #159. Part of #154.

) Two tiers in the new test/agent/policy_check/: - test_conflict_check_live_llm.py (-m llm, deselected by default): drives check_policy_conflicts end-to-end through the real LLM with only the catalog seam (focal_entities._config) stubbed and _structured_call left live. Planted direct + coarse-scope + clean fixtures on the scope-focal branch (Tool focus). Structural assertions only: clean => no_conflict; planted => confirmed set contains the planted (role, scope) pair, and every returned quote is a verbatim whitespace-normalized substring of policy_text (reusing the engine's _verify_quote). Skips cleanly when LLM env is unset. - test_apply_conflict_regression.py (deterministic, default suite): pins the unchanged live contract -- build_role_rules raises PolicyContradictionError on a genuine contradiction, and POST /apply/service/{id} maps it to 422 with the PCE never called.

Adds a clean read-only POST /policy/check diagnostic that fans out the full proposer→precheck→audit PRB assembly over every focal entity, records all conflicts without aborting, and returns a single ConflictReport — the design, models, routing logic, and test coverage are all solid.
Two nits inline; neither blocks merge.

Nit: config.get_services() is called here to derive service_type, and then resolve_focal_entities calls config.get_services() again internally (line 85 of focal_entities.py). The config object is passed through correctly, so this is two IdP round-trips for the same catalog data. Worth passing service_type (and the already-fetched services list) directly into resolve_focal_entities in a follow-up, or caching the result on config, to halve the catalog reads per request.

Good catch — confirmed, two get_services() round-trips per request. Deferring to a follow-up (not this PR) because resolve_focal_entities is shared with the live /apply builder and its docstring deliberately forbids deriving service_type from focus.type. Clean fix: add an optional pre-fetched services param to the resolver and thread the already-fetched list through, keeping the /apply contract byte-for-byte. Tracked in rossoctl/rossoctl#2476.

Nit: Import ordering — aiac.agent.uc.policy_check.check is inserted before aiac.agent.uc.offboarding.offboard, but alphabetically offboarding < policy_check. CI pre-commit passes (ruff/isort agrees with this), so it's not a blocker, but worth a quick ruff check --fix sweep on this file to keep the block tidy.

Fixed in 760eebb via ruff check --fix (imports now sorted offboarding < onboarding < policy_check). Note: ruff does flag this locally (I001) — it slipped through CI because the pre-commit ruff hook is scoped to authbridge/, so aiac/ files are not linted. Worth widening that scope separately.
|
Efficiency suggestion (non-blocking): check_policy_conflicts fetches the IdP catalog (get_services()) once itself for the service_type lookup, then resolve_focal_entities fetches it again internally — two IdP round-trips per check request where one would do. Flagged with a nit that no test currently asserts the call count, so this is easy to miss. |
Reorder the uc.* imports in controller/routes.py so offboarding < onboarding < policy_check, resolving ruff I001. The aiac/ tree is outside the repo pre-commit ruff scope (authbridge/-only), so this was not caught in CI. Import-only change; no behavior change. Addresses a review nit on #154.

This PR delivers the complete Policy Conflict Check feature (#154) — a read-only pre-commit diagnostic that surveys all focal entities of a target service at once and returns a ConflictReport with verbatim, substring-validated quotes. The implementation is well-structured: D13 refactor (resolve_focal_entities) is a clean extraction with no behavior change to the live path, the forked diagnostic assembly reuses _propose/_precheck unchanged, and the test coverage is thorough across all three tiers.
Two minor observations below.

Nit (perf): double get_services() call per request. check.py calls config.get_services() here to derive service_type, then passes config into resolve_focal_entities — which also calls config.get_services() internally. The config object is correctly shared (single seam for test patching), but the catalog is fetched twice on every POST /policy/check. For a read-only diagnostic endpoint this is low priority, but worth noting. One approach: accept an optional pre-fetched services list in resolve_focal_entities, or extract focus from the entity set after the resolver returns it.
There was a problem hiding this comment.
Confirmed and tracked separately in rossoctl/rossoctl#2476 (the config seam is shared correctly; only the catalog fetch is doubled). Deferred from this PR because resolve_focal_entities is shared with the live /apply builder and its docstring forbids deriving service_type from focus.type; the fix threads a pre-fetched services list through, keeping /apply byte-for-byte.

Nit: policy_text: str accepts empty strings. AC#4 specifies "missing policy_text ⇒ non-2xx" — FastAPI's required-field 422 covers the missing case, but "" passes validation and will flow through the full survey, almost certainly landing on status: incomplete or no_conflict (zero grants/denies = nothing to conflict). If an empty canvas should be rejected at the HTTP boundary, a Field(min_length=1) would enforce that. If an empty policy triggering incomplete is an acceptable/expected result, a docstring note would help future readers.
There was a problem hiding this comment.
Documented in f4203be (chose the docstring option). Empty policy_text is a well-formed request surveyed like any prose — with no grants/prohibitions to collide it lands on no_conflict (or incomplete if zero focal entities evaluate), never conflicts_found. AC#4 only requires a missing field to be non-2xx (FastAPI 422), and an empty draft returning "no conflict" is an honest result rather than a boundary error, so no min_length gate was added.

Address review feedback on #154 (PR rossoctl#809). Correctness (was: silent drop -> clean masquerade): _explain joined the auditor's free-form Contradiction.candidate_name against this run's typed candidate set, and on a miss it 'continue'd silently. precheck filters the PROPOSER's name lists, not the auditor's candidate_name, so a confirmed contradiction against an unjoinable name was dropped with no trace -- and if it was the only one for the entity, the survey classified the entity clean and the report could reach no_conflict while a contradiction was confirmed. Now mark the focal entity Unevaluated(reason=unjoinable_candidate) so its presence forces status to incomplete (never no_conflict). New UnevaluatedReason enum member + regression test; existing enum-values test updated. Docs: declare POST /policy/check final in the sub-PRD (remove the settled /policy/check vs /policy/conflicts open item) -- the route shipped as /policy/check and PRD/component specs already say so. Docs (route): document that an empty policy_text is a well-formed request that surveys to no_conflict/incomplete (never conflicts_found), not a 422 -- AC#4 only requires a *missing* field to be non-2xx. Not changed (by design): quotes_verified=True with one empty quote side is intended per US#18 (description-derived grants carry no citation); a quoting FAILURE is what sets quotes_verified=False (US#19). The double get_services() fetch is tracked separately in rossoctl/rossoctl#2476. Assisted-By: Claude (Anthropic AI) <noreply@anthropic.com> Signed-off-by: Anatoly Koyfman <anatoly@il.ibm.com>

Summary
Adds a separate, read-only pre-commit policy conflict diagnostic that a caller invokes before onboarding/committing a policy. Given candidate policy prose and a target service, it surveys that service's focal entities against the live IdP catalog, runs the same proposer → precheck → audit machinery the live
/applypath uses, and — instead of aborting on the first genuine contradiction — records every genuine contradiction and continues, returning a singleConflictReportthat lists all conflicts at once.Each reported conflict carries the colliding
(role, scope)pair (name + id), the conflictkind(direct or coarse-scope granularity mismatch), verbatim, substring-validated quotations of the granting and prohibiting statements, and a plain-language explanation. A clean policy reportsno_conflict("No conflict."); a survey where zero entities could be evaluated reportsincompleterather than masquerading as clean.This is a diagnostic gate, not the commit. It never mutates policy state and the live
/apply→ 422 contradiction path is left byte-for-byte unchanged.Changes
